Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of caliper is performed by user, then measurement can be performed, but user labor increases and measurement efficiency decreases
Solution Approach 1:
The measurement apparatus performs measurement operations automatically without requiring manual caliper placement by the user. The system autonomously identifies measurement targets, determines measurement lines, and calculates measurements based on acoustic wave images, enabling self-service measurement that eliminates user labor while maintaining measurement functionality
Solution Approach 2:
The patent replaces the mechanical manual operation system (user physically placing calipers) with an automated image processing system that uses computational algorithms to identify measurement targets and calculate measurements from acoustic wave images, substituting mechanical user actions with electronic automation
2Measurement precision
If manual caliper input is required, then measurement function is available, but user experience and proficiency affect measurement quality
Solution Approach 1:
The system automatically performs measurement without requiring user skill or experience. The automated algorithm independently identifies measurement targets, determines appropriate measurement lines, and calculates results, eliminating variability in measurement quality that arises from differences in user proficiency while maintaining consistent measurement accuracy
Solution Approach 2:
The system incorporates feedback mechanisms where the measurement apparatus analyzes acoustic wave images, identifies measurement targets, and automatically adjusts measurement parameters to ensure accurate results. This feedback loop ensures measurement precision is maintained regardless of user capability by continuously optimizing the measurement process based on image analysis
3Productivity
If automated measurement is implemented, then user labor is reduced, but system complexity increases
Solution Approach 1:
The automated measurement system is divided into distinct functional modules: measurement target recognition unit, measurement line determination unit, and measurement calculation unit. Each module performs a specific function independently, making the complex system manageable and maintainable while achieving automated measurement efficiency
Solution Approach 2:
The measurement apparatus is designed to handle multiple measurement scenarios universally. The same automated system can measure different types of targets (tumors, organs, lesions) and perform various measurement operations (length, area, volume) through a single integrated platform, achieving high productivity without proportionally increasing complexity
